Below item level 50, these weapons can generally be used by either a Arcanist, Summoner or Scholar, although there are a few exceptions. Above item level 50 these weapons are generally split into those that can be used by Arcanists and Summoners, and those that can be used by Scholars - there are some exceptions however, of books above level 50 that can be used by all three, and books which can only be used by a Summoner, such as its Relic Weapon.
